Twenty years of Arctic research puts Denmark on the world map. In 1995, visionary researchers established the Zackenberg Research Station in North-East Greenland to monitor climate change in the area. Today – twenty years later – the climate change is precisely described in a unique data set.

Animals graze around half the land on Earth, affecting the plants that grow there, the soil, and the carbon sink. Now, a team from Lund University, Sweden, and Aarhus University in Denmark has found that excluding muskox (Ovibos moschatus) from mires in Greenland reduces their carbon uptake but increases their methane emissions.
